The quality of images is relevant in building compression and image enhancement algorithms. Image Quality Assessment (IQA) is divided into two main areas; reference-based evaluation and no-reference evaluation.
Reference-based methods rely on high-quality images to evaluate the difference between two images. Structural Similarity Index is one example of a reference-based method. Unlike reference-based methods, however, no-reference methods don’t require a base image for evaluating the quality of an image. These methods just receive an image whose quality is being assessed.
